Check Digit Verification of cas no

The CAS Registry Mumber 397332-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,7,3,3 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 397332-07:
(8*3)+(7*9)+(6*7)+(5*3)+(4*3)+(3*2)+(2*0)+(1*7)=169
169 % 10 = 9
So 397332-07-9 is a valid CAS Registry Number.
